Add a kill_sessions tag to exclude tests in concurrency simultaneous replication suites

There are a few tests that are excluded from multiple concurrency simultaneous replication suites for having killSessions commands. Instead of individually listing the tests to skip, create a kill_sessions tag to exclude and add it to the list of tags for all affected tests. 

Suite yml files to be updated: 

• concurrency_simultaneous_replication.yml
• concurrency_simultaneous_replication_wiredtiger_cursor_sweeps.yml

• concurrency_simultaneous_replication_wiredtiger_eviction_debug.yml

Tests to add tag to:

• jstests/concurrency/fsm_workloads/internal_transactions_kill_sessions.js
• jstests/concurrency/fsm_workloads/multi_statement_transaction_kill_sessions_atomicity_isolation.js
• jstests/concurrency/fsm_workloads/multi_statement_transaction_simple_kill_sessions.js
